I am attempting to troubleshoot an intermittent charging issue on my 75 R90S with the stock Bosch alternator. I had seen a flickering GEN light at road rpm. I thought I'd first test the regulator as described below: REGULATOR TESTS: In case the Regulator is faulty and preventing the Alternator from charging, perform the following tests: TEST 1H: 1. Disconnect the D+ and DF wires from the Regulator and join these wires temporarily together so as to bypass the Regulator completely. NOTE: Check the wiring at the Regulator connector for corrosion or overheating - gently pull the wires to check they are secure. 2. Start the engine and see if the Charge light goes out - if so, the Regulator is likely faulty. When I turned on the key I didn't have the usual GEN light just the Neutral and Oil Pressure. I started the bike and revved up to 2000-3000 rpm but no change in the GEN light, it stayed unlit. What does this indicate?
